"\.VARPINGMACHINE ATTACHENT.

Specification of Letters .Patent Patented Apr. 5, 1910.

Application filed April 23, 1909. Serial No. 491,838.

To all whom it may concern.'

Be it known that l, THOMAS A. Moonina citizen of the United States, residing in Clifton, Passaic county, New Jersey, have` invented a Certain new and useful lmprovei vpart of this specilication. i

It is Well known that when certain mate-f rialsesilk, for instance-are manipulated` in `such a Way as to produce friction, difficultyy in handling the same according to-tlie predetermined purpose is niet with in 'the forni of disturbances arising out of tstatic electricity. For instance, iii the operation of Warpirne silk, it is known that the friction of the silk due to rubbing contact with parts of the apparatus causes the silk to fly, z'. e., each thread or'lainentu tp repel `its neighbor, so that` the silk not only spreads itself unduly; making thersetions or bands of Warp of irregular or unintended "width, but piles nnevenly in the 'successive windings on the reel. The exciting medium in the case just referred to is the reed or reeds of the warpingl machine, and l have discovered that if an electrical conductor is extended from suchpart of the apparatus to the point ivliere the electrical disturbance manifests itself such disturbance Will be eliminated; in other Words, by providingI such a conductor the repelling tendency is neutralized.

So far as I ani able to see, this is due to the fact that, since tlietendency of the threads to repel each other is m'l at or adjacent their point of contact with the exciting medium, by employing an electrical con- .ductor I extend the saine eect to the point tion with a Iwarping mill, Figure l being a side view of such an apparatus, showing my improvement attached thereto; Fig. is a vertical sectional view of the carriage of the machine showing one of the reeds and my improvements iii side elevation; Fig. 3 is a plan view of the attachment forming my improvement.

ln the drawings, a designates the frame of-a warping machine, Z) its reel, c its car- 1 riapje, and c the usual reeds and j the usual rollers arranged on the carriage. The silk -g or other material beingl warped extends through the reeds, under one roller f, over the other roller f and around the reel Z), y

resting on the slats iz, of the latter.

In practice it is found that the existence of static electricity in the material g, caused by its contact, While moving, with the reeds d and c, and particularly with the reed (l, causes the `threads to ily, as above stated, that is, to repel each other; this phenomenon manifests itself in a portion of the material between the reel and the nearer roller f. so that instead of the material being laid on the reel in bandsI or sections of constant or iutended Width, it is caused to be laid on the reel in irregular or unintended disposition, the warp sections being too wide in places or piled irregularly. As above stated. in order 4to overcome this l. provide an electrical conductor which extends from. the exciting medium, in the present instance the reed or reeds, to the point-where the electrical disturbance manifests/itself` to wit, iii proximity to the portion of the material g disposed between the reel and the nearer roller tij.' To this end c' is a metallic plate which may-be suitably secured, asliy screws j,to the carriage c, the screws preferably penetrating slots /c so that the plate, Which stands horizontally, may be adjusted toward and from the rcel. The plate z' has arms Z projecting toward the reel and in the ends of these are journaled truiinions m on upwardly'projecting arms n of a bar 0. The rear portion of' the bar 0 extends back ofthe arins n and yin its front port-ion are mounted'a number of parallel pins y? preferably having pointed ends. The rear part g of the bar 0 forms a counterweightfor the pins so that the normal position of the coinb'formed by the bar and pins is in a plane forming a right anglev oith a tangent of the reel. The comb being pivoted it will yield should any of the inaterial catch upon its points, which extend into as close proximity as possible to the portion r of the material disposed between the reel and the nearer roller f; the' comb of course yields in both directions, so as to accommodate itself to backward as Well as forward rotation of the reel.

It will be understood that the comb is metallic as Well as plate z'. From one of the screws j extends a Wire or other metallic conductor s which is attached to the metal holder t in which the reed d, (also of metal) is mounted; as'shown in Fig. l, at s, this conductor is electrically connected also with the reed e.

When an attachment of the nature of that above described is applied to a warping machine or the like, it Will be found that the disturbances due to the existence of static electricity in the material are entirely overcome. For instance, in the operation of lwarping, instead of the sections or bands of Warp being laid on the reel irregularly (for instance, in such a Way that a cross-section of any pile would reveal a more or less triangular form), the material is laid on the reel uniformly and in regular and intended widths, so that a cross-section of any band or section of Warp on the reel would simulate a rectangle.

I-Iavinv thus fully described my invention, what I c aim as new and desire to secure by Letters Patent is:

1. The combination, with means for operating' upon the material comprising a part as bet-Ween which and the material there is relative movement, of a conducting means leading from said part into proximity to the point where static electricity set up in the material by said part manifests itself, the portion of said means proximating the material being a metallic comb, substantially as described.

2. The combination, with means for operating upon the material comprising a part as between which and the material there is relative movement, of' a conducting means leading from said part into proximity to the point Where static'electricity set up in the material by said part manifests itself, the portion of said means proximating the material being a metallic comb yieldable in the direction ot'L relative movement as between the material and said part, substantially as described.

3. The combination, with means for draW- ing threads lengthwise and a part with which the threads have contact, of a conducting means leading from said part int-o proximity to the threads at a point between the first means Iand said part, substantially as described.

4. The combination, with means for drawing threads lengthwise and a part With which the threads have contact, of a conducting means leading from said part into proximity to the threads at a point between the first means and said part, the portion of the conducting means proximating the material being a metallic comb, substantially as described.

5. The combination, With means for drawing threads lengthwise and a part with which the threads have contact, of a conducting means leading from said part into proximity to the threads at a point between the first means and said part, the portion of the conducting means proximating the material being a metallic comb yieldable in the direction of movement of the threads, substantially as described.

6. The combination of a suitable supporting means, a part jrurnaled therein on which to Wind the material, a art with which the material has contact Whi e being advanced to the rotating part, a metallic comb projecting into proximity to the rotating part, and means for electrically connecting the comb with the second named part, substantially as described.

In testimony, that I claim the foregoin I have hereunto set my hand 22nd day o April, 1909.
